    CPU temp -- is this running too hot ?


    Hi there

    running a fairly heavy but not unduly load the CPU seems to be running at about 75 deg C peak -- Avg about 61 deg C.
    Is this likely to cause trouble over prolonged periods.

    I know that these devices can run extremely hot but I don't want to break it if adding more cooling can sort it out.

    Any hardware gurus out there --is this OK or should I try and take remedial action.

    Ideally CPU temp should be in 35~45 C and for laptop it will be a little higher. Your temp is high but still within range. However, if you do some heavy Audio/Video Editing then the temp will raise up to hell. Try to clean up with dust blower and double check if the heatsink is properly seated. You might also want to put new thermal paste on the CPU.

    Here's what mine look like running @4.7GHZ but again I am using H2O cooling.

    Hi there

    That's more like what I'd expect.

    I've been doing some video transcoding which is probably quite heavy but cpu at idle still seems to run at around 40 deg C.

    I rather am dubious of trying to break it open to add thermal paste etc --the CPU was supplied as a unit with the whole heat sink / fan assembly as a package. I'll also see if a bigger (or another) fan inside the case will make any difference.

    The room in which the computer is in runs at around 20 - 22 deg C with the other equipment working so not overtly hot.

    Haven't got the luxury of Water cooling on this computer !!.

    Cheers

    For a veteran of these forums, you don't help by giving the hardware specs of the machine you are enquiring about (slap wrist)!

    Have you made sure the chipset drivers are recent Intel/AMD/Nvidia etc., rather than Microsoft generic versions that came with Win 10, jimbo?
    see the stickies at the top of this Drivers and Hardware forum for the main updaters and analysers for your system.

    These can make differences with extra wait cycles, CPU throttling etc. The right Rapid storage drivers, and Speedstep configuration all help to reduce bottlenecks, and thus temperature. There may be BIOS adjustments too that may be tweaked, which will make a difference in core temperatures.

    As an aside, the P4 in my spec always has been notorious as a CPU that tends to run hot, it regularly soars to above 75 when both the threads are at 100%, occasionally hitting the 90s - and that's in an 11-y-old processor, and when idling gets as cool as 57 deg only. But there is no throttling, so it always gives its all, which is very different from modern multi-core CPUs.

    That's normal - don't do anything.

    All CPUs work much hotter under duress.
    Handbrake in particular is a right ******* when it comes to racking up the core temps!
    Your idle temps are what they should be.
    If these are your maximum temps you are posting then your system is running exactly how it should be... at least temperature wise.

    ...but I don't want to break it if adding more cooling can sort it out...
    Do it if it gives you peace of mind.
    CPUs switch themselves off before they get too hot.

    I agree. 40C at idle is normal. 60C or 70C under a load is normal.

    I recently purchased a refurbished 4 year old business desktop. CPU temperatures at idle were 60C. I took off the CPU fan/heat sink and the thermal compound was totally dried out. I cleaned heatsink and CPU top surface (an old plastic credit card works great to remove dried thermal compound without scratching metal surfaces) and applied new thermal compound. Now idle temps are 37C to 40C. So if you have a system that is a few years old and unexplained high CPU temps, check the thermal compound.
